When starting the engine, the engine
switch may seem stuck in the “LOCK”
position. To free it, turn the key while turn-
ing the steering wheel slightly left and
right.
WARNING
■ When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the

2304-5. Toyota Safety Sense
YARIS_F_WE_52G04E
■Operational conditions
The pre-crash safety system is enabled and determines that the possibility of
a frontal collision with a vehicle (e xcept motorcycles and bicycles) is high.
● Pre-crash warning:
• Vehicle speed is approximately 15 to 140 km/h (10 to 86 mph).
• The relative speed between your vehicle and the vehicle ahead is greater
than approximately 15 km/h (10 mph).
● Pre-crash brake assist:
• Vehicle speed is approximately 30 to 80 km/h (19 to 49 mph).
• The relative speed between your vehicle and the vehicle ahead is greater
than approximately 30 km/h (19 mph).
● Pre-crash braking:
• Vehicle speed is approximately 10 to 80 km/h (7 to 49 mph).
• The relative speed between your vehicle and the vehicle ahead is greater
than approximately 10 km/h (7 mph).
When the brake pedal is stepped on, the system judges if evasion actions are
being done by the driver and the start timing for pre-crash braking may be
delayed.
During the following, the driver operations takes precedence and the system
may not operate:
● The accelerator pedal is depressed strongly
● The steering wheel is turned sharply or abruptly
In case of the following, the system will not operate:
● If a battery terminal has been disconnected and reconnected and then the
vehicle has not been driven for a certain amount of time
● If VSC is disabled (only the pre-crash warning function will be operational)
● If the PCS warning light is flashing or illuminated
● When the shift position is in R
■ Cancelation of the pre-crash braking
● If either of the following situations occur while the pre-crash braking function
is operating, it will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is turned sharply or abruptly.
● If the vehicle is stopped by the operation of the pre-crash braking function,
the operation of the pre-crash braking function will be canceled after the
vehicle has been stopped for approximately 2 seconds.

Winter driving tips
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect the condition of the battery.
● Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the front tires.
Ensure that all tires are the same size and brand, and that their wear level
is not noticeably different with each other. Also make sure that chains
match the size of the tires.
Perform the following according to the driving conditions:
● Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing.
● To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
● Check for and remove any excess ice or snow that may have accu-
mulated on the exterior lights, vehicle’s roof, chassis, around the
tires or on the brakes.
● Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a man-
ner appropriate to the prevailing weather conditions.
